Can you explain what Ansible Vault is and what it is used for?

Ansible Vault is a tool in Ansible that allows encrypting sensitive data such as passwords, API keys, and other secrets used in automation. It helps securely store and transmit sensitive information alongside playbooks and inventory files.

Main features of Ansible Vault:

• Encrypting and decrypting secret files.
• Integration with Ansible playbooks for automatic use of encrypted data.
• Ability to edit encrypted files using the ansible-vault edit command.

Example of creating an encrypted file:

ansible-vault create secrets.yml

Example of using an encrypted file in a playbook:

- hosts: all
  vars_files:
    - secrets.yml
  tasks:
    - debug: msg="Password: {{ db_password }}"

Thus, Ansible Vault ensures security when working with secrets in infrastructure as code.
